Question
A metallic ring connected to a rod oscillates freely like a pendulum. If now a magnetic field is applied in horizontal direction so that the pendulum now swings through the field, the pendulum will
- Keep oscillating with the old time period
- Keep oscillating with a smaller time period
- Keep oscillating with a larger time period
- Come to rest very soon
The correct answer is: Come to rest very soon
Emf induces in ring and it will opposes the motion. Hence due to the resistance of the ring all energy dissipates.
